RNA polymerase I mutant affects ribosomal RNA processing and ribosomal DNA stability
Transcription is a major contributor to genomic instability. The ribosomal RNA (rDNA) gene locus consists of a head-to-tail repeat of the most actively transcribed genes in the genome.

Alterations of the mitochondrial proteome caused by the absence of mitochondrial DNA: A proteomic view [PDF]
The proper functioning of mitochondria requires that both the mitochondrial and the nuclear genome are functional. To investigate the importance of the mitochondrial genome, which encodes only 13 subunits of the respiratory complexes, the mitochondrial rRNAs and a few tRNAs, we performed a comparative study on the 143B cell line and on its Rho-0 ...

Quantitation of Human Ribosomal DNA: Hybridization of Human DNA with Ribosomal RNA for Quantitation and Fractionation [PDF]
Extract: Quantitation of human genes for ribosomal RNA (rRNA) was possible by molecular DNA/RNA hybridization on nitrocellulose discs. Labeled ribosomal RNA hybridizes with an average of 14 × 10-5 of the total human DNA. If we assume that the diploid cell contains 5.5 × 1012 daltons of DNA, the ribosomal RNA hybridizes with 7.7 × 108 daltons of ...

Phylogenetic and phyletic studies of informational genes in genomes highlight existence of a 4 domain of life including giant viruses. [PDF]
The discovery of Mimivirus, with its very large genome content, made it possible to identify genes common to the three domains of life (Eukarya, Bacteria and Archaea) and to generate controversial phylogenomic trees congruent with that of ribosomal genes,

Nucleotide Excision Repair is one of the five DNA repair systems. More than 30 proteins are involved in this process, including the seven XP proteins. When mutated, the genes coding for these proteins are provoking the rare disease Xeroderma Pigmentosum,

Modular Golden Gate Assembly of Linear DNA Templates for Cell-free Prototyping [PDF]
Cell-free transcription and translation (TXTL) systems have emerged as a powerful tool for testing genetic regulatory elements and circuits. Cell-free prototyping can dramatically accelerate the design-build-test cycle of new functions in synthetic biology, in particular when linear DNA templates are used.

Ribosomal protein S3: A multifunctional target of attaching/effacing bacterial pathogens
The extraribosomal functions of ribosomal proteins have drawn significant recent attention. Ribosomal Protein S3 (RPS3), a component of the eukaryotic 40S ribosomal subunit, is a multifunctional protein that regulates DNA repair, apoptosis, and the ...
